This study uses your blood or genetic information to make “iPS cells,” lab-grown cells that can help researchers study inherited heart rhythm problems like LQTS, Brugada syndrome, CPVT, or early repolarization syndrome. It may help improve understanding of why these rhythms happen and guide future treatments.
Baltimore, MarylandAges 18–85 - NCT02814942Recruiting
Testing CRT in people with weak hearts and wide ECG signals
This study looks at whether a device called CRT (Cardiac Resynchronization Therapy) can help people with heart failure who have a weak heart pumping strength and a “wide” electrical signal pattern on an ECG. It may help some people feel better and improve heart function, especially if they are not already on the best standard medicines.
SingaporeAges 18 years+ - NCT01725763Enrolling by invitation
MRI without contrast to help diagnose pulmonary hypertension

Balloon in aorta to improve CPR for in-hospital cardiac arrest
This trial tests if placing a balloon in the main artery (aorta) during CPR can improve blood flow to the heart and brain. It is for adults who have a cardiac arrest while already in the hospital and have a pulse-check showing some heart activity.
BernAges 18 years+ - NCT07435168Recruiting
Chest pain and hidden cardiac amyloidosis study
This study looks for signs of a condition called cardiac amyloidosis in people who have chest pain but no blocked heart arteries. It aims to find hidden cases that might be missed with standard tests.
CopenhagenAges 65 years+ - NCT07436962Recruiting
Loop recorder for mitral valve heart condition
This trial tests whether a small heart monitor (loop recorder) can help people with a specific mitral valve condition called mitral annular disjunction. It's for patients who have scar tissue in their heart muscle shown on an MRI.
BudapestAges 18–60 - NCT07464938Recruiting
Predicting brain recovery after cardiac arrest
This study is testing new tools and markers to better predict recovery after cardiac arrest when brain injury may occur. It involves adults who had a cardiac arrest outside the hospital and are being treated at Saint-Luc hospital.
BrusselsAges 18 years+ - NCT07472296Recruiting
Comparing nerve blocks for heart surgery pain relief
This trial compares different types of nerve blocks to see which works best for managing pain after heart surgery through the breastbone. It may help reduce the need for strong pain medications.
Bursa, NilüferAges 18–80 - NCT07481396Recruiting
Studying brain injury after cardiac arrest through spinal fluid
This trial is looking at the spinal fluid of people who survived a cardiac arrest outside the hospital and are being treated for brain injury. The goal is to learn more about brain damage and find new ways to help patients recover.
Daejeon, Jung-guAges 18 years+ - NCT07483047Recruiting
Predicting memory changes after heart surgery in older adults
This study looks at older adults having heart surgery to find out who might have trouble thinking or remembering afterward. Researchers hope to build a tool to predict this risk so doctors can help sooner.
ShanghaiAges 65 years+ - NCT07483151Recruiting
Heart Surgery and Thinking Changes Study
This study looks at how changes in blood flow (called venous congestion) after heart surgery might affect thinking and memory. It aims to find out if there is a link between how blood returns to the heart and brain function after surgery.
Yangzhou, JiangsuAges 18 years+ - NCT06617377Recruiting
Can MRI predict brain recovery after cardiac arrest?
This study uses brain scans (MRI) to try to predict whether people who are still unconscious after a cardiac arrest will recover. It is looking for adults who are in a coma and have not woken up after being taken off sedation medicines for at least three days.
ToulouseAges 18 years+ - NCT07511673Recruiting
Dental screening before heart valve surgery
This trial tests whether a dental checkup before heart valve surgery can improve recovery and prevent complications. If you are scheduled for a heart valve procedure, you may be able to join.
GothenburgAges 18 years+ - NCT07532174Recruiting
Blood-Cleaning Device During Heart Surgery
This trial tests a special blood-filtering device (Efferon LPS) used during heart surgery to reduce inflammation and improve recovery. The device removes harmful substances from your blood during the operation.
